This is the final version of replacing my 20 years old "lava lamp" that runs with a 60 watt bulb and needs at least 1 hour to warm up.The new version uses 20 RGB-LEDs each controlled by a single WS2812 RGB-Controller. It uses only 5 or 6 watt and providing 8 different modes that are controlled by a Arduino pro mini 328 5V/16MHz board. The potentiometers with knobs are used to switch between the modes and control speed, color or brightness of the several modes.The LEDs are glued on a wooden staff placed inside a smoothed acrylic glass cylinder. It took about two days creating this lamp including soldering the 120 pads and about 70 wires, crafting the mechanical part and writing the Arduino-Sketch that gets the lamp to life.
